Mavic Rear Black Crossmax wheel spec as follows:
1997 /98 Mavic CrossMax: S.U.P., Ceramic rims, 28 spoke rear, radial non-drive, cross 3 drive, 850g, FTS hub FTS Hub: found on CrossMax wheels, forged hub body
Let me know if you have one or see one on your cyber travels
Went through this a few months back with my crossmax. If you can find one cheap fairplay. If not mavic have them but want Â£120 for new rim, spokes and build.
Ended up getting a bog standard 517 in black and rebuilding with the old spokes. Had plenty of abuse so far, sweet as a nut.
